His name on Percy's lips like that, sent tingles down his spine in a most pleasant way. Or maybe it was the feeling of Percy's fingers through his hair or his lips against his. Not that he cared. It felt good, right even, and he wasn't about to question it.
Still, when he felt himself respond a bit too much, he broke the kiss, forcing his body to calm down. 'You should probably sleep if you're tired,' he said softly, though he made no move to pull back or let go of his embrace. He liked feeling Percy's body so close, and didn't want to change that.
